API 600/BS1414 Gate Valves
The API 600 gate valve is divide into two big types by sealing surface configuration, include wedge-type gate valve and parallel-type gate valve, wedge gate-type valve can be divided into: single-disc gate valve, double-disc gate valve and flexible-disc gate valve; the parallel-type gate valve can be divided into single-disc gate valve and double-disc gate valve. According to location of the thread on the stem, the division can be divided into rising API600 gate valve and non-rising gate valve.
Pressure seal forged gate valve
The first one is the bolted-bonnet gate valve cover, according to the form of this design of valve design, the valve body and valve cover with bolt nut connection, spiral wound gasket (316 folders manufacturing flexible graphite) seal. the special requirements of customers can also connect the metal ring.The second design is a form of welding-type valve cover, according to this design form of the valve, the valve body and valve cover with threaded connection, all-welded seal.
